Single Storey Rear, Double Storey Side Extension, Loft Conversion & Porch

  PLANNING AUTHORITY BROMLEY COUNCIL For our clients at 21 Rafford Way we really went to town. There wasn't one single part of this semi detached property in Bromley that wasn't effected by the proposed designs. Our clients wanted a complete make over with interior designs, internal remodel, double storey side extension, singe storey rear extension and loft conversion with modern dormer, sliding doors and juliet balcony. The single storey rear extension included a lovely pergola over the new flush patio area which then lead in through large format sliding doors to the new open plan Kitchen/Diner with island unit. We designed the roof lights in a way so they extended up over the apex of the roof structure creating an atrium style effect with clear views to the sky above. This in turn allowed us to create a Laundry Room, downstairs WC, and separate Utility Room getting all that clutter away from the nice new Kitchen area. The double storey side extension created a larger Bedroom at the rear of the property, a new Ensuite and larger more luxurious Master Bathroom all in all providing much needed additional space at first floor level. A unique and well designed loft conversion at the next level up provided a further Living/Entertainment area. With the added box dormer, sliding doors and balcony this created an amazing outlook over the garden area. A truly unique space for our clients to enjoy with friends and family.

For our clients at 21 Rafford Way, Bromley we undertook a complete Architectural Design Services comprising of the following Project Brief:

  • Demolish existing attached outbuilding including chimney stack and conservatory to rear of property. Demolish double storey side extension to the LH side of property making room for new double storey LH side extension, plus single storey rear extension.
  • Rear Extension and Landscaping Work:
  • Build new single storey extension to rear.
  • Suggest going into rear garden with extension 6m from existing main house rear wall (not conservatory wall) and going full width of house plus width of new side extension allowing for single side access within the permitted boundary.
  • Demolish existing dining room/kitchen external rear walls, plus existing kitchen external side wall to form large, luxurious open plan Kitchen continuing into new side extension.
  • This will provide a fantastic large open plan rectangular space for your Kitchen perfect for incorporating an island unit/breakfast bar and dining table.
  • Add bi-folding or frameless sliding doors to rear elevation maximising natural light in Kitchen bringing the outside in. I would also like to design a further option with a window over the sink just to make sure we have considered everything. This will also provide a nice outlook over the garden.
  • Dig out rear garden and allow for a new patio from the extension with steps leading to a second level which will be reduced in height to the floor level of the rear gate.
  • Raise new patio area creating flush floor finish through doors into Kitchen. In summer with the doors open this creates a seamless transition between outside and inside effectively making the Kitchen feel even larger. Particularly if new raised external patio area is fitted with identical tiled floor finish to Kitchen/Diner.
  • Replace Hallway/Kitchen door with a glass door which will provide an amazing light and airy outlook all the way from the front entrance door to the back garden. This will create that critical first impression ‘wow’ factor when coming through the front entrance door.
  • Provide windows to side extension.
  • Form new ground floor Family Room in current Dining Room position by extending the existing internal dividing wall to the new rear elevation.
  • Take out existing fireplace in Family Room and Lounge allowing for new feature fireplaces.
  • Recommend new wet under floor heating system to Kitchen and Family Room connected to new boiler to be located in Utility.
  • Form new ground floor Utility Room/Boot Room in LH side of the Kitchen with an external door to side alley and another door opening into Kitchen/Diner. This will provide an alternative entry to your house rather than having to go through your nice new Kitchen every time. The Utility Room in effect doubles up as a Boot Room where you can come into the house with muddy shoes, dog etc and hide it all away from the main Kitchen/Diner which can be kept nice and clean. As a Utility Room it doubles up as an overspill from the Kitchen where you can have your washing machine, tumble dryer, back up fridge freezer etc. maybe even a sink to wash the muddy shoes. Utility Rooms are great when you have guests and family around as you can pile up some of the dishes in there for washing up later. Some of our clients have even put a second dishwasher in here which can be quite handy.
  • Form a Study Room to the front of the LH side extension.
  • Remove the existing downstairs shower and reconfigure a design allowing for a ground floor WC. with separate coat cupboard.
  • Redesign the stairs to give access to the new landing area.
  • Front drive/steps to be taken to road level.
  • Extension roof:
  • New flat roof, (customers preferred choice) – Can incorporate large over-hanging roof such as image 10 attached. Can also incorporate LED lights. Creates a nice modern contrast to a traditional property, also easy to incorporate glass skylights maximising natural light in this area. System flat roofs can create an even more modern roof finish. They are high performing, come with good guarantees, must be installed by approved installers but are more expensive. They create a seamless, slick, smooth modern finish. See image 8 and 10.
  • Side Extension and First Floor Configuration:
  • Provide access to the LH first floor extension via the new reconfigured landing.
  • Remove the bay to the front LH bedroom and replace with a flat four section window.
  • Front RH bedroom to become the Master Bedroom with a new Walk-In Wardrobe/En-suite to the LH side created by removing the internal dividing wall to the existing LH bedroom and utilising the side extension.
  • Existing rear RH bedroom to remain the same.
  • Create a further two bedrooms and Master Bathroom to the rear and balance of the new side extension.
  • Adding French doors/side panels with Juliet balconies to any rear bedrooms means that in summer the French doors can be opened right up, again bringing the outside in and creating a nice balanced look with the windows/doors in the loft conversion. Privacy can be maintained with integral blinds. See images 21-25.
  • Loft Conversion:
  • This would create an additional Bedroom and En-suite at 2ndfloor level.
  • As discussed you have a hipped roof design and we have a method that will get you even more available space in your loft. Current planning relaxations mean that we can get you a full height loft for almost the entire foot print of your current loft floor area. If you have hipped roof you need to take advantage of this now before it expires.
  • We recommend forming a gable end in the new extended roof design in case the loft conversion does not fit the budget at this present time.
  • Add a box dormer to rear roof pitch which maximizes the available full head height floor space. These box dormers are much better than they used to be and can be finished in various colours of wall tiles, horizontal modern wood effect planks or coloured ‘K’ render. All these solutions are pretty much maintenance free and never need to be painted again. We can even install double French doors, with full height side glass panels and Juliet balconies providing more natural light and ventilation to this room and providing an amazing outlook over your garden. Have a look at images 35 to 43 to get an idea of the different finishes available.
  • Install 2 Velux roof windows on front roof pitch bringing in more natural light to this front part of the loft.
  • Ideally the staircase to the new loft rooms would go above the existing staircase and we will incorporate with the new staircase/landing designs.
  • Ideally we would install a Velux roof window above the loft staircase bringing in natural light and ventilation to this area which can become quite dark due to it being located centrally in your property. (see images 44 to 51).
  • Ancillary Work:
  • Remove/re-fit new coving/skirting/internal door frames/doors to the existing rooms and re-plaster all walls.
  • With a well-designed and properly planned out loft conversion and double storey side extension, plus rear single storey extension including internal conversion work your property would increase in value considerably with you now having four/five generous sized Bedrooms, two En-suites, a new Study, Family Room, plus Master Bathroom also an open plan Kitchen with separate Utility Room which are all currently in high demand in the property market.
  • Estimated construction budget £200,000 - £250,000 (Excluding Kitchen/Bathrooms)
